Abstract: A hinge is mounted between a cover and a base of an electronic device and has a supporting bracket, a rotating bracket, a mounting bracket and a pintle. The supporting bracket is connected to the base, and the rotating bracket is connected to the cover. The mounting bracket is attached to the supporting bracket and has a positioning wing and two sleeves. The pintle is attached to the rotating bracket, is mounted through the mounting bracket and has a flat wall. The flat wall of the pintle selectively abuts against the positioning wing of the mounting bracket to hold the cover at a desired position. The abrasion between the sleeves and the pintle balances torque.

Abstract: A hinge has a pintle, a spacer assembly, a stationary bracket and a rotating bracket. The pintle is mounted through the spacer assembly and is connected to the stationary and rotating brackets. The spacer assembly has multiple spacers stacked with each other. Each spacer has a ring segment and a bearing segment. The ring segment is mounted around the pintle. The bearing segment has an absorbing space to absorb the stress acting on the ring segment. Therefore, the spacer sustains less stress to prevent breakage easily and a lifespan of the spacer is extended. Therefore, the hinge has a longer lifespan.

Abstract: A torque-adjustable hinge is mounted between a display panel and a base of a portable device and has a stationary bracket, a rotating bracket, a pintle, a torsional spring and an adjusting element. The stationary bracket is attached to the base. The rotating bracket is attached to the display panel. The pintle is attached to the rotating bracket and is mounted through the torsional spring. The torsional spring is attached to the stationary bracket and abuts against the adjusting element. By changing the height that the adjusting element protrudes above a receiving tag of the stationary bracket, the torsional spring is selectively tighter or looser wound around the pintle. Therefore, the torque generated by the hinge is adjusted without replacing any element.

Abstract: A hinge is mounted between a cover and a body of an electronic device and has a sheath, a shaft and a positioning unit. The sheath is connected to the body and has a flat panel. The shaft is connected to the base, is mounted through the sheath and has a flat surface. The positioning unit is attached to the flat panel and has an undulated positioning member selectively abutting the flat surface of the shaft to provide positioning function and to enhance the largest torque. Moreover, the undulated positioning member increases the contact points between the shaft and the positioning unit so that the shaft is stable during rotation.

The supporting bracket is connected to the base and the rotating bracket is connected to the cover. The mounting bracket is attached to the supporting bracket and has a positioning wing and two sleeves. The pintle is attached to the rotating bracket, is mounted through the mounting bracket and has a flat wall. The flat wall of the pintle selectively abuts against the positioning wing of the mounting bracket to hold the cover at desired position. The abrasion between the sleeves and the pintle balances torque.

Abstract: A coaxial cable adapter includes: an outer sleeve pipe, having an inserting slot with a straight aperture disposed therein; a rubber gasket, formed by a straight cylindrical soft rubber, and disposed in the inserting slot of the outer sleeve pipe; and an inner sleeve pipe, having a metal locking head and a plastic cylindrical pushing pipe respectively disposed on two ends of a central pipe, in which one end of the central pipe extends out of the pushing pipe. When the inner sleeve pipe and the outer sleeve pipe are joined, the soft rubber gasket is deformed and filled in the gaps of the adapter to wrap a cable, thereby achieving a better inner waterproofness. Meanwhile, as the adapter has an entirely metal case, its strength is also enhanced.

Abstract: A pivotal hinge has a seat and a shaft, and a first end of the shaft is inserted into the seat. A second end of the shaft is inserted into multiple washers, a first and a second positioning ring, multiple elastic rings and a cushion ring in turn. The first positioning ring can be positioned relative to the second positioning ring and with the friction force of the washers, the excellent position effect can be achieved. Hence, a cover of a laptop computer can be positioned to the chassis of the laptop computer at a desired height.

Abstract: A resilient flat washer has a ring and a keyed wing. The ring has an inner annular edge, an outer annular edge and at least one inner abrasion flange. The at least one inner abrasion flange is formed longitudinally on the inner annular flange. The keyed wing is formed transversely on the outer annular edge. A hinge has a stationary leaf, multiple resilient flat washers and a pintle. The resilient flat washers are mounted in a sleeve of the stationary leaf. The pintle is mounted rotatably in the rings and has a pivoting rod. The pivoting rod abuts the at least one inner abrasion flange, so the contact area between each resilient flat washer and the pivoting rod are increased. Therefore, the friction provided by the resilient flat washers is enhanced.

Abstract: A hinge has a stationary leaf, multiple resilient flat washers and a pintle. The stationary leaf has a sleeve. The resilient flat washers are mounted in the sleeve and each resilient flat washer has a ring and a key wing. The ring has a receiving recess formed in a first surface and a mounting rib formed in a second surface. The receiving recess of each resilient flat washer engages the mounting rib of a corresponding resilient flat washer. With the engagements of the receiving recesses and the mounting ribs, the resilient flat washers are connected to each other to enhance the strength of the resilient flat washers. Therefore, the resilient flat washers are strong enough to bear the abrasion for long term use.
